Preliminary Information | |
---|---|
Leak Risk | High |
Batteries | None |
Destructive Entry | No |
Known Issues
Symptom or Problem Encountered
Sometimes there's no hot water.
Causes
- Even if the timer activates, the relay does not always trip when the heating relay is active at the same time.
Solutions
- The relay and microcontroller supply are derived from a capacitative dropper circuit. Replacing the yellow X2 capacitor restores the voltage supply.
Disassembly Notes
Remove the three screws from the back side. One is under a tamper warning sticker.
The back slides off over the power pins. The battery can be left in place.
